CVD-graphene growth on different polycrystalline transition metals

open access: yesAIMS Materials Science, 2017
The chemical vapor deposition (CVD) graphene growth on two polycrystalline transition metals (Ni and Cu) was investigated in detail using Raman spectroscopy and optical microscopy as a way to synthesize graphene of the highest quality (i.e.

Crystal and Magnetic Structures in Layered, Transition Metal Dihalides and Trihalides

open access: yesCrystals, 2017
Materials composed of two dimensional layers bonded to one another through weak van der Waals interactions often exhibit strongly anisotropic behaviors and can be cleaved into very thin specimens and sometimes into monolayer crystals.

Stable Monolayer alpha-Phase of CdTe: Strain-Dependent Properties [PDF]

open access: yes, 2017
CdTe is a well known and widely used binary compound for optoelectronic applications. In this study, we propose the thinnest, free standing monolayer of CdTe which holds the tetragonal-PbO (alpha-PbO) symmetry. The structural, electronic, vibrational and

Monolayers of fatty acids. II. Stearic acid on aqueous solutions containing solutes with alcoholic functional groups

open access: yesGrasas y Aceites, 1991
The structure and the stability of stearic acid monolayers spread on aqueous solutions with glycerol, glucose or sucrose are studied using a commercial film balance (Lauda). The experiments were carried out isothermically.

Room Temperature Intrinsic Ferromagnetism in Epitaxial Manganese Selenide Films in the Monolayer Limit

open access: yes, 2018
Monolayer van der Waals (vdW) magnets provide an exciting opportunity for exploring two-dimensional (2D) magnetism for scientific and technological advances, but the intrinsic ferromagnetism has only been observed at low temperatures. Here, we report the

2D- and 3D-Based Intestinal Stem Cell Cultures for Personalized Medicine

open access: yesCells, 2018
Colorectal cancer (CRC) is one of the most common cancers that have high occurrence and death in both males and females. As various factors have been found to contribute to CRC development, personalized therapies are critical for efficient treatment.

Imaging Spin Reorientation Transitions in Consecutive Atomic Co layers

open access: yes, 2006
By means of spin-polarized low-energy electron microscopy (SPLEEM) we show that the magnetic easy-axis of one to three atomic-layer thick cobalt films on ruthenium crystals changes its orientation twice during deposition: one-monolayer and three ...
